Description

Technical Field

[0001] This utility model relates to the field of air preheating technology, and in particular to a small co-current high-temperature air preheater. Background Technology

[0002] An air preheater is a heat exchange surface in the boiler's tail flue gas duct that preheats the air entering the boiler to a certain temperature through internal heat exchange fins. It is a device used to improve the boiler's heat exchange performance and reduce energy consumption. Air preheaters are generally divided into three types: plate type, rotary type, and tubular type. The working principle of an air preheater is introduced using a rotary type as an example. A large amount of unburned combustible material may accumulate on the heat transfer elements, potentially causing an air preheater fire. Therefore, the causes of such fires are analyzed, and the causes and countermeasures are explained in detail. The analysis of circuit breaker tripping and leakage control are also described in detail.

[0003] Most existing small-scale co-current high-temperature air preheaters are relatively fixed and cannot be adjusted according to work requirements to be installed in a specific location. As a result, they cannot perform to their full potential, which will affect their use.

[0004] To address these issues, we propose a small, co-current high-temperature air preheater. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a small-scale co-current high-temperature air preheater.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a small co-current high-temperature air preheater, comprising:

[0023] The device includes a small air preheater 1 and a mounting base 2. The small air preheater 1 is existing technology and can preheat air. The mounting base 2 is coated with a protective coating that adheres to the outer wall of the mounting base 2, thereby improving the strength of the mounting base 2 and increasing its service life. Multiple self-locking casters 3 are fixedly connected to the mounting base 2, which can move the entire device to the working position. The mounting base 2 has a working groove, and a working turntable 4 is rotatably connected in the working groove. The other end of the working turntable 4 is fixedly connected to a working connecting block 5 through a disassembly and assembly assembly. The disassembly and assembly assembly includes a disassembly and assembly connecting plate 16 fixedly connected to the outer wall of the working connecting block 5 near the working turntable 4. The disassembly and assembly connecting plate 16 and the working turntable 4 cooperate with each other. Multiple disassembly and assembly bolts are also installed on the disassembly and assembly connecting plate 16, which can facilitate disassembly and installation by the staff while ensuring stable installation.

[0024] The working block 5 has a working slide groove, and a working support 6 is slidably connected in the working slide groove. The end of the working support 6 away from the working block 5 is fixedly connected to the small air preheater 1, so that the working support 6 can drive the small air preheater 1 to move together. Adjustment component: The adjustment component includes a threaded sleeve 7 rotatably connected to the inner wall of the working slide groove. A working screw 8 is threadedly connected to the threaded sleeve 7. The end of the working screw 8 away from the threaded sleeve 7 is fixedly connected to the working support 6, so that the working screw 8 can drive the working support 6 to move together. A bevel gear 9 is fixedly connected to the threaded sleeve 7. A working shaft 10 is also rotatably connected in the working slide groove. One end of the working shaft 10 rotatably passes through the working slide groove. A working handle is fixedly connected to the working shaft 10. The working handle is disc-shaped. The working handle and the working shaft 10 cooperate with each other, making it more convenient for the operator to rotate the working shaft 10.

[0025] A bevel gear 11 is fixedly connected to the other end of the working shaft 10. The bevel gear 1 and bevel gear 11 mesh with each other, so that rotating the working shaft 10 can drive the threaded sleeve 7 to rotate through gear meshing transmission. A limit plate 12 is also fixedly connected to the inner wall of the working slide groove. The working screw 8 slides through the limit plate 12. The limit plate 12 is provided with a limit key, and the working screw 8 is provided with a limit keyway. The limit key and the limit keyway cooperate with each other to limit the working screw 8, so that it only slides along the direction of the threaded sleeve 7. A rotating assembly is also installed in the mounting base plate 2. The rotating assembly includes a working cavity opened in the mounting base plate 2. A support column 13 is rotatably connected in the working cavity. One end of the support column 13 rotatably passes through the working cavity. The support column 13 and the working turntable 4 are fixedly connected and installed, so that when the support column 13 rotates, it can drive the working turntable 4 to rotate together. A working worm gear 14 is fixedly connected to the support column 13, and a working worm 15 is also rotatably connected inside the working cavity. One end of the working worm 15 rotatably passes through the working cavity. The working worm gear 14 and the working worm 15 are meshed with each other, so that rotating the working worm 15 can drive the support column 13 to rotate through the worm gear meshing transmission. A stabilizing plate is fixedly connected to the inner side wall of the working cavity. The working worm 15 rotates through the stabilizing plate, thereby ensuring the working position of the working worm 15 and avoiding problems such as falling off.

[0026] In the process of using this utility model, the staff first pushes the overall device to the working position, and then rotates the working shaft 10 according to the installation environment, so that the bevel gear 11 fixedly connected to the working shaft 10 rotates. Due to the meshing characteristics of the gears, the bevel gear 9 will also start to rotate, thereby driving the threaded sleeve 7 to rotate. Due to the characteristics of the threaded connection, the working screw 8 will drive the working bracket 6 to move under the limiting action of the limiting plate 12, thereby driving the small air preheater 1 fixedly connected to the working bracket 6 to move together. Then, its height can be adjusted according to the working environment to make it in the position with the highest working efficiency.

[0027] Next, the operator rotates the working worm 15. Due to the meshing transmission characteristics of the worm gear, the working worm wheel 14 will start to rotate, which in turn drives the support column 13 to rotate together. This, in turn, drives the working turntable 4, which is fixedly connected to the support column 13, to rotate together. This adjusts the orientation of the small air preheater 1 so that it can be placed in a position that is convenient for connection. Finally, the operator only needs to connect the small air preheater 1 to the external equipment to start working.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
